Title: Reference voltage generating circuit
Inventor: KIMURA KATSUHARU
IPC: G05F3/24
Filed: 1992-02-05
Abstract: PURPOSE:To obtain the reference voltage generating circuit suitable for a CMOS integrated circuit. CONSTITUTION:A ratio of capability of transistors(TRs) M1, M2 is 1:K1 then gate-source voltages of them differ from each other. TRs M3, M4 are components of a current mirror circuit and the ratio of the capability of the both is K2:1. That is, the M1, M2 are driven by a current ratio of K2:1. As a result, the temperature characteristic of the mobility and the temperature characteristic of a threshold voltage are cancelled together and the reference voltage generating circuit with an excellent temperature characteristic is realized on a CMOS integrated circuit. Furthermore, an output reference voltage VREF is used in the presence of a resistor R1 and a reference voltage VREF1 is used when the resistor R1 is omitted. Or a voltage branched from a gate of the M2 may be used (VREF2) for the reference voltage and a reference voltage extracted from a drain of the M2 provided with a resistor may be used.

IPC: G11B11/105
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient reproducing signal even when reproducing is performed based on a small recording bit diameter and a small recording bit interval by arranging a magnetic mask layer between a reproducing layer and a recording layer composed of a vertical magnetizing film magnetically connected with the reproducing layer for suppressing magnetic connection between the recording layer and the reproducing layer at a room temperature to be away from the reproducing layer. SOLUTION: An intrasurface magnetizing layer 3 is formed as a magnetic mask layer adjacent to a recording layer 4, magnetization from a part 11 not heated over a critical temperature in the recording layer 4 is masked by the intrasurface magnetizing layer 3. In other words, by the intrasurface layer 3, the influence of the magnetization of the part 11 of the recording layer 4 on a reproducing layer 1 is prevented. Thus, the mask of only a part over the critical temperature is eliminated and, even when a magnetic area existing in the reproducing layer 1 is larger in size than a recording magnetic area, information regarding only a desired magnetic area heated over the critical temperature in the recording layer 4 is reproduced.
